(SOCHI, RUSSIA) — Hilary Knight scored less than a minute into the first period to help the U.S. women’s hockey team defeat Finland 3-1 in the opening match of the Sochi 2014 Olympic Winter Games tournament.

The Americans scored twice in the second period on goals from Kelli Stack and Alex Carpenter. Carpenter gave the USA its first power play goal of the tournament.

Finland’s Susanna Tapani scored on a power play at 55:22 to break up the shutout.

– If it feels like winter will never end, look on the bright side: The cold air and snowy streets are giving you a workout and you don’t even know it.

So relish the remaining weeks — consider them boot camp for spring — and check out these five ways winter makes you fitter:

It Boosts Your Metabolism

As your body shivers to keep warm, it converts calorie-storing white fat into calorie-burning brown fat, according to a new study published in the journal Cell Metabolism. It turns out all that tooth-chattering releases the hormone irisin — the same hormone released during a workout. Thanks to irisin, your cells release more heat, helping your body maintain its internal temperature, according to study author and National Institutes of Health researcher Dr. Francesco S. Celi. “Perhaps lowering the thermostat during the winter months could help both the budget and metabolism,” Celi said in a statement.

It Challenges Your Muscles

All that shoveling and plodding through snow is a real workout for your muscles, which have to work even harder in the cold. The low temperatures also dampen your flexibility, so stay stretched and your muscles will be supple for spring.
It Makes You Sleep More

The longer nights of winter lengthen your body’s melatonin signal — the molecular cue for bedtime. This can help you fall asleep and stay asleep. Take advantage of the natural sleep aid to get a good night’s rest, but don’t overdo it: Sleeping too much has been linked to obesity, diabetes and heart disease.

It Helps You Hydrate

Winter is primetime for soups and teas — tasty ways to get your water. Broth-based soups packed with veggies make a healthy meal, but beware the sodium content. Some store-bought soups use salt as a flavor boost. When it comes to tea, try something minty. Peppermint green tea is a refreshing way to warm up without the dehydrating effect of caffeine.

It Motivates You

Remember those New Year’s resolutions? You’ve had January to think about them, and now it’s time to act. Whether you want to lose weight, gain muscle, quit smoking or eat healthier, winter is a great season to hunker down and get it done. Just think how great you’ll feel when spring arrives.

Take Care in the Cold

While winter can help you get fit, make sure you do it safely. Low temperatures raise the risk of hypothermia and frostbite, and heart-related deaths are more common in the colder months. So bundle up if you’re going outside and don’t overexert yourself.

GoPro, the company known for its small wearable cameras has filed paperwork that would allow it to become a publicly traded company.

CEO and Founder of GoPro Nick Woodman started the company with $64,000 of his own money and $10,000 from his father. Now, GoPro cameras are sold in 50 countries around the world. Analysts have estimated the company’s 2013 sales at near $1 billion.

The filing of paperwork was done under the rules of the 2012 JOBS act, which allows the company to keep its sales and operational information confidential for now.

There has not yet been a date set for GoPro’s initial public offering.

Pizza, according to a new National Health and Nutrition Examination Survey from the USDA.

The survey, called “What We Eat In America,” looked at data from 2007 to 2010, and the study concluded that one in eight Americans “consumed pizza on any given day.” And the rate went up to 1 in 4 when looking at American boys and men between the ages of 6 and 19.

The study also found that men eat more pizza than women, and white Americans eat more pizza than other groups.

A Colorado woman says offering her breast to her new puppy was a last ditch effort when the puppy would not drink from a bottle or canine formula.
The woman, who is not being identified, says the last resort occurred to her to offer the puppy her own breast when he was not taking other food.

“He just wasn’t taking it, I didn’t know what else to do I was desperate. I just couldn’t bear sitting there watching him die,” she said. “I never thought I would ever do that but… It was taboo to me as well. I guess you could call it in a sense it’s like a maternal instinct.”
Veterinarian Dr. Amber Williams does not recommend humans breast feeding animals as there are diseases that can be transmitted from the puppy to human babies. And, she says, it may not be great for the dog either.
“I’m more concerned about zoo-notic disease because there are things that can be passed from… puppies to babies,” Dr. Williams said. “In an emergency situation, I don’t think it’s a big deal but for them to grow appropriately, I think it would be important for them to get on a canine formula.”

Fashion house Valentino is facing harsh criticism for a PR blast it sent out a day after Philip Seymour Hoffman’s wake, using a photo of actress Amy Adams as she attended the event to advertise its newest handbag.

The offending release was coupled with pictures of the actress arriving with her husband Darren Le Gallo at Hoffman’s private wake, which was held Thursday at Frank E. Campbell Funeral Home in Manhattan.

Hoffman, 46, died last Sunday of a suspected drug overdose in his Manhattan apartment.

Adams, who co-starred with Hoffman in the 2012 film The Master, Doubt in 2008, and Charlie Wilson’s War in 2007, was not aware that her name was being used for Valentino’s publicity, a representative for Adams confirmed to ABC News Saturday.

“Amy Adams is not a paid spokesperson for Valentino, and the suggestion she would use this moment to participate in a promotion is truly appalling,” spokeswoman Megan Moss ­Pachon said in a statement.

Khosla did not respond to ABC News’ request to comment but the fashion house released a statement on Friday saying it was “not aware the photograph was taken while she was attending the wake of Philip Seymour Hoffman” and that Adams was “not aware, or a part of, our PR efforts.”

Valentino’s press office later tweeted another apology saying it was an innocent mistake: “We regret releasing a photo of Amy Adams with a Valentino bag. Unaware of the circumstances it was a mistake and we apologize to Ms. Adams”

The death of actor Philip Seymour Hoffman has highlighted the plight of some 369,000 Americans addicted to heroin.

Use of the drug – an opiate similar to morphine – is on the rise in the United States, nearly doubling between 2007 and 2011 when 620,000 Americans reported using heroin at least once, according to the Substance Abuse and Mental Health Services Administration. In the same year, use of the drug led to nearly 260,000 emergency room visits.

Whether injected, inhaled or smoked, heroin quickly enters the brain to cause a euphoric rush. But the high comes with a dangerous drop in blood pressure and respiration, which can be fatal.

Heroin is also highly addictive, luring almost a quarter of those who use it into dependence, according to the National Institute on Drug Abuse. Medications like methadone and buprenorphine, which activate the same brain receptors as heroin, can help reduce cravings and dampen withdrawal symptoms. But for some, the treatments are no match for heroin’s addictive high.

“The research shows that about 60 to 70 percent of people who use medications like buprenorphine or methadone are still in treatment after one year,” Dr. Jason Jerry, a professor of medicine with the Cleveland Clinic’s Alcohol and Drug Recovery Center, told ABCNews.com. “Only 10 to 20 percent of patients who are completely detoxed and off of everything manage to stay clean for an extended period of time.”

Hoffman was found dead Sunday with a needle stuck in his arm and buprenorphine inside his New York City apartment, according to police. The Oscar-winning actor had been sober for 23 years before relapsing into addiction.
